In the zero-gravity airplanes or vomit comet, why does stuff behave like there is no gravity when it is just falling? – Austin B., 11, Scranton, Pennsylvania I have flown many times in zero-gravity ...
A: I have flown many times in zero-gravity airplane flights. Each time I still enjoy the feeling of floating free, the ability to fly across the cabin from just one gentle push on the wall, just like ...

Windfall lesson We intuitively learn the basics of gravity from observing things falling, like apples from trees. But there is a lot more to the subject than Isaac Newton and black holes. (Courtesy: ...
Gravity warps space in strange and counter-intuitive ways, and the bigger the source of gravity, the bigger the warping. One example of gravity’s optical illusions is beautiful rings in space named ...
Measuring the strength of gravity is extraordinarily difficult, and different experiments have always disagreed – but a new ...
Physicists have traced three of the four forces of nature — the electromagnetic force and the strong and weak nuclear forces — to their origins in quantum particles. But the fourth fundamental force, ...
